*2 A PC (hereafter referred to as Setting PC) is required to make settings for the AE-50/EW-50 BACnet
disconnect the Setting PC from the AE-50/EW-50. Refer to section 7 "Checking installation operations and performing trial run" for
details.
*3 If using the apportioned electricity billing function, we recommend that instead of using the AE-50/EW-50 built-in Pulse Input (PI), the PI
controller be used for measurement of electric energy.
(If AE-50/EW-50 built-in Pulse Input (PI) is used, pulse input will not be possible when the AE-50/EW-50 is stopped, during power
outages or during software updates. This could result in discrepancies between the measurements and the actual electric energy
consumed.)
When using the AE-50/EW-50 built-in Pulse Input (PI), approve the above-mentioned restrictions for the customer and then use.
*4 Up to 50 units of equipment can be connected to and controlled by each AE-50/EW-50. Up to 4 AE-50/EW-50 controllers can be
connected to each AE-200 for billing function.
*5 To use an apportioned electricity billing function and perform date and time synchronization from the building management system, set
the "Time Master/Sub" setting to "Sub" on the AE-200 for billing function and synchronize the time from AE-50/EW-50 connected to
®
BACnet . The "Time Master/Sub" setting can be made on the Initial Setting Tool, Web Browser for Initial Settings, or AE-200/AE-50's
LCD. (Refer to the AE-200/AE-50/EW-50 Instruction Book (Initial Settings) for settings methods.)
*6 If using the apportioned electricity billing function, connection of M-NET and Pulse Input (PI) to the AE-200 for billing function is
prohibited. Accordingly, the AE-200 for billing functions does not have any BACnet
necessary. As a result, BACnet
*7 If using the apportioned electricity billing function, connection of LAN1 for transfer of power apportioning information is required.
